Whole Body Vibrations during Fully Mechanised Logging

Frequency-weighting Curve for Whole-body Vibrations

In a laboratory experiment, six male subjects were exposed to sinusoidal (0.8, 1.6, 3.15, 6.3 and 12.5 Hz) or random octave band-width white noise (mid-frequencies identical to those of the sinusoidal vibrations) whole-body vibration in xor y-directions, at six levels of magnitude (0.4, 0.8 and 1.6 m/s2 r.m.s. nonand frequency-weighted) with two repetitions. In order to examine time effects, ad...

Whole body vibration exercise: are vibrations good for you?

Whole body vibration has been recently proposed as an exercise intervention because of its potential for increasing force generating capacity in the lower limbs. Its recent popularity is due to the combined effects on the neuromuscular and neuroendocrine systems. Preliminary results seem to recommend vibration exercise as a therapeutic approach for sarcopenia and possibly osteoporosis. This rev...

Audiotactile simultaneity perception of musical-produced whole-body vibrations

Everybody has sometimes experienced the vibrations generated by the performance of music. The floor or the seat place can vibrate because of the resonance or the structureborne sound stimulated by instruments. When these vibrations are correlated with airborne sound, they are additional information for us. The correlation between vibration and airborne sound might be important in implementing, ...

Effect of whole body vibrations on sound localization

Electromyographic response during whole-body vibrations of different frequencies with progressive external loads

The purpose of this study was to analyze if exposure to whole-body vibrations (WBV) of different frequencies with none or additional loads from 20 to 50 kg promotes changes in EMGrms activity of the quadriceps and gastrocnemious muscles. Sixteen male subjects with previous experience in strength training volunteered to participate. Subjects received the treatment while standing on a vibration p...
